void ckernel::softplus_tile_init()

Please refer to documentation for any_init.

void ckernel::softplus_tile(uint32_t idst, uint32_t beta, uint32_t beta_reciprocal, uint32_t threshold)

Performs element-wise computation of softplus (1/beta * log(1 + exp(beta * x))) on each element of a tile in DST register at index tile_index. Any input value greater than the provided threshold with return itself. The DST register buffer must be in acquired state via acquire_dst call. This call is blocking and is only available on the compute engine.

Return value: None
